1. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland
University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskapAbstract : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. READ MORE

2. Evaluating the Performance of Propulsion System Elements in an Aerospace Company
University essay from KTH/Kraft- och värmeteknologiAbstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. READ MORE

3. Parametric investigation of a theoretical organic rankine cycle
University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknikAbstract : The energy resource waste heat or low-grade thermal energy is available in vast quantities. Tapping into this resource and converting it to electrical energy would not only reduce energy waste but also has the potential to eliminate greenhouse gas emissions. READ MORE

4. The effect of autocorrelation when performing theapproximated permutation test
University essay from Uppsala universitet/Statistiska institutionenAbstract : In meteorology, permutation tests are a commonly recommended tool because standard paramet-ric methods of inference often is insufficient when analysing weather. Therefore other methodswith less stringent assumptions like permutation testing is used. READ MORE

5. Modeling of the trajectory of ice thrown from a wind turbine
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.
